The sticker itself lands perfectly at two. It is the accumulating that does not.

What to do instead
Use the sticker as the whole reward, given immediately, with the thing named out loud as you hand it over. No total, no target, no chart with a finish line. "You put your cup on the side. That's a star." The naming is doing most of the work and the sticker is holding their attention while you do it.
When the chart part starts working
Depends which kind. A chart that finishes today — three boxes and something small when the third is filled — works from about three, and there is a version built for that age. A chart that accumulates, where Monday's stickers are still worth something on Friday, needs about five or six.
The signal for the second kind is when they start asking how many they have, unprompted. Before that a running total is mostly a craft project for the adult, which is fine, but it is worth knowing that is what it is.
What the year in between is for
It is not a year of waiting. Everything a chart eventually does rests on a habit that has to be built first, and it is entirely buildable at two: saying the thing out loud as it happens. A child who has spent a year hearing their actions described in plain words arrives at four already understanding that what they do gets noticed, which is the part a chart formalizes.
The other thing worth doing early is watching which things are genuinely hard for this particular child. At two you will find out whether transitions are the problem, or noise, or being asked to stop something enjoyable. Those are the lines that will go on the chart in two years, and knowing them in advance is worth more than any template.
What to avoid before four
Anything with a target the child can miss. A chart with five boxes and a prize at the end is, to a two-year-old, an object with stickers on it and a grown-up who is sometimes disappointed. Nothing is gained, and something is spent: you have used up the novelty of the whole idea on a version that could not have worked.
